ai <br />Orange County 7rigon Project No D3G-00.OIGII <br />Hillsborough Landfill Site _ 7uly 24. 2000 <br />3.1.2 Groundwater Sampling <br />Iwo, Type II growndwater monitoring wells were installed in the central portion of the <br />site (see Figure 3). The wells were installed on either side of the creek that divides the <br />landfilled area because this was determined to be a likely discharge point for groundwater <br />and potentially leaclrate generated from the land£II. Following installation, these wells <br />were developed, purged and sampled in accordance with the Groundwater Section <br />Guidelines for t/re Investigation mrd Remediation Gf Soi( and Grroundwater, Volume II, <br />Ianuary 2, 1998.. Groundwater was measured at approximately 5.2 feet below ground <br />surface in MW-1, and approximately 1.3 feet below ground surface in MW-2. Boring <br />logs, including well construction details, aze included in Appendix A. <br />3.2 SOIL AND GROUNDWATER ANALYSES RESULTS <br />3.2.1 Soil Analyses Results <br />The four soil samples collected in Febntary 2000 from in and around the baseball field, <br />and the sample collected from the central portion of the property and the two well borings <br />in April and May, 2000 were submitted to Paradigm Analytical Laboratories- The <br />samples were analyzed for volatile organic compounds (VOCs) by EPA Method 8260B, <br />semi-volatile organic compounds (SVOCs) by EPA Method 8270, pesticides and PCBs <br />by EPA Method 808Q, and RCRA and priority pollutant metals. A summary of the <br />analyses results are provided in Table 1 below. <br />No VOCs, SVOCs, pesticides or PCBs were detected above their respective quantitation <br />limits in any of the soil sanrples With the exception of arsenic in six of the seven <br />samples, including the background sample, no metals were detected at concentrations <br />above their respecfrve Remediation Goals (RGs} established by the North Carolina <br />Department of Environment and Natural Resources (NC DENR) pursuant to the Inactive <br />Hazardous Sites Response Act of 1987 (N,C.G.S. 1.30A~310 et. se9.).
